Thru-Hull Transducer?
 

A boat "mechanic" told me that a thru-hull transducer can also give the water temp to your depthfinder. I find that hard to believe, but I definitely don't know everything when it comes to technology today.

a thru- hull actually has contact with the water because it is installed through your hull. I believe you mean an in-hull transducer. They will also give you water temp, i have had one. I think it's because the bottom of the boat is in contact with the water and so is the same temp as the water

Yes sorry, I did mean in-hull. Unit is a Garmin which I am not familiar with was afraid would just be reading the hull temp and not the water temp. few degrees can make a difference.

I'm thinking about installing an in hull transducer. Have an Lowrance unit and lose depth once I accelerate. Does it work well for you at any speed?

idk if my response will help but we glued our standard transducer to the bottom of our bay boat, and we never had a problem reading depth and it picked up temperature too. It takes a little longer for it to acclimate to the actual water temp sense its in the hull but it worked good enough for us. It had to be accurate to about 2-3 degrees if I had to guess

sounds like you transducer needs to be adjusted or is installed too high on your transom. In hull will work at any speed as long as its installed in the right spot. My in-hull was just a standard transducer glued to the hull also
